On CAPS, 63% of the 35 members who have rated ServiceSource believe the stock will underperform the S&P 500 going forward. These bears include robertshrestha and All-Star TSIF, who is ranked in the top 0.1% of our community.

Just last week, robertshrestha listed several of ServiceSource's negatives: "Heavy insider selling, weak operating margins, high P/E, no obvious moat that I can see. Not much to like here."

In fact, ServiceSource sports a particularly lofty price-to-sales ratio of 6.6. That represents a clear premium to rivals Accenture (1.4), Oracle (3.9), and SAP (3.3).

CAPS All-Star TSIF elaborates on the ServiceSource bear case:

Insiders sold 9 Million shares the first week of August in a secondary, mostly insider offering ... can't blame them for cashing out, but they have more to dump and they relieved the float. Service Source is a "cloud" play with management services for subscription based company's. Anything with Cloud in it is getting some focus, both in speculating about growth potential and/or a takeover by those trying to expand their cloud reach. ...

IPO's are tougher to forward value, but at 7X book, negative cash flows and mixed margins, I think this one's a wait and see.
